Feature Sort Table Columns

**Instructions:**

Add an `onClick` handler to the columns of the result table, which sorts the results ascending (A -> Z). Clicking the column again will reverse the sort order to descending (Z -> A).

**Hint:** Try using the `.sort()` method with a callback to do custom sorting.

**Test:**

- [ ] Each column in the table should be clickable to sort results in ascending or descending order.
